In the drawings the numerai 1U indicates the receiver, to the rear portion of which a stock 11 is secured by suitable means such as a tang screw 121. A barrel 12 is likewise secured to the receiver in a manner to be hereinafter described; The receiver 10 contains the breech block 14, the hammer'l and the The present improvements are particularly applicable to riiies of the type commonly called single shot rifles in which a fired shell is ejected and a fresh cartridge manu- V ally inserted for each operation. On accountof the manual operation of this type of gun, it is desirable to provide certain safeguards against incomplete and improper manipulations which are automatically prevented'in guns of the repeating or self loading type. Y

It is an object of the present invention to provide a gun which will require a certain sequence of operation for ejecting and reloading, which precludes the possibility of `premature firing or accidental discharge when the breech is not properly locked.

A further object of the invention is to provide an improved firing spring and pilots for this spring which prevent abnormal displacement or misfunctioning. A further object of the invention is to utilize a part of the breech block as an abutment for the firing spring and in this manner to cause the firing spring to control the movement of thebreech block as well as the hammer. VA further object of the 'invention is to provide an improved means for retaining the iire control lmechanism in place when the barrel is removed.

VVith these and other objects in view, the invention consists in the novel combination and arrangements of parts, a representative embodiment of which is shown in the illustrative drawings and will be hereinafter described.

In the drawings:

Fig. 2 is a fragmentary longitudinal sectional elevation showing the mechanism in loading position. l

trigger 16, and carries the trigger guard 17.

rlihe breech block is pivoted at 18 and eX- tends rearwardly and upwardly to form the chamber closing head 19, from which a knurled finger piece20 extends laterally as shown in Fig. 5. A firing pin 21 extends through the head 19 and is recessed to receive rthe shank 201 of the nger piece 20, which n' thus acts as a retaining pin.

The hammer is provided with two notches 25 and 26 respectively, adapted to be engaged by the nose 27 of the trigger. The notch 25,

which holds the hammer in intermediate or half cockedposition is adapted to engage the trigger nose in such a way as to prevent release of the `hammer from this position. It

is necessary that-the hammer be fully cocked I K before it can be released for firing movement. The hammer is also provided withY a shoulder 23 which is substantially concentric with the pivot 22 and with second shoulder 24, both of which are adapted for cooperation with the heel 231 of the breech block. gun isV closed the shoulder 23 engaging the heel 231 serves as a breech lock. A thrust upon the breech block tending to rotate it about its pivot 18is transmitted through its engaging surfaces in a line passing through the pivot 22. Thus movement/of the hammer to breech releasing position is prevented.

When the action is in half cocked position as shown in Fig. 2, the heel 231 engages the lower shoulder 24 of the hammer stopping the downward movement of the breech block. VVhe'n the hammer is drawn to fully cocked position the heel 24 moves upwardly carrying the breech bloc-k into a position in which it obstructs the insertion or removal of a cartridge or shell from the chamber.

The ring movement of the hammer is effected by means of a coil spring 28 carried upon spring pilots 29 and 30 which engage respectively with suitable recesses in the When the tractor.

of pilot 30 after which the spring urges 'the breech block downwardly. A sing-le yspring is thus made to function as a firing spring and the vmeans for yieldingly retaining the breech block in either closed or open position.

Pivoted in the forward endof the breech Vblock member at 3l is an extractor 32 within a recess vin the breech block and partly in the bar-rel. The extractor comprises an upturned forked end 33'for engagement with the shell rim and a forwardly extending toe 34 overlying a shoulder 35 on the receiver.

The extractor is urged counter clockwiserby spring' occupying Va recess in the breech block and engaging the lower edge' ofthe eX- The invention contemplates both improved means for securing the forearm tothe barrel and an improved 'take down device. The

vforearm 40 is heldto the 'barrel by means of a screw 41 which enters a threaded o eninfr C vin the barrel. A countersunk opening in the forearm receives the screw anda metal cup 42 which contains the screw head and protects the wood of the forearm against wear and abrasion by the screw. The barrel is secured to the receiver by a take down device .constructed as follows: f

Apl'ug 45 is received in a threaded'recess in the barrel and is -tightlyfitted therein. The plug comprises an extending shank 46 which 4is counterbored and threaded to receive the enlarged and threaded end ofthe take down screw 47. The enlarged-and threaded end-of screw 47 occupies ,a countersink inthe receiver metal vand canonly be 'removed by turning through the threads .of the screw shank receiving opening 48; The screw 47 is manipulated by'means of a knurled head 49.

The operation of the mechanism is as follows ' lV'hen'fit is desired to load the gun the ham `mer must be moved to half cocked position as shown in F ig. 2, in whichposition'it is locked against firing movement. If the hammer is mov-ed to fully cocked position the breech'block iselevated bythe engagement of heel 231 with shoulder 24 and prevents the insertion of a cartridge. A cartridge having been placed in the chamber with the hammer in half'cocked position the gun may be carried if desired,l without closing the breech and Vwith the hammer either half cocked or,

Leaavo fully cocked, the cartridge being heldin the chamber by the extractor 29, which is urged into frictional engagement with the cartridge by its spring 36. The hammer may be cocked but if an attempt is made to fire the gun without the breech being closed, the forward face 152 of the'hammerA merely engages the rear face ofthe breech block preventing any part of the hammer coming in contact ,with the firing pin.' Thek breech -being properly closed Vis heldin closed position by the pressure of thefiring spring 28, the hammer may then be released by pressure on the trigger and as it falls the shoulder23 engaging the heel 231 effectively locks the breech before the hammer strikes Ithe firing pin. The 'gun-being fired the hammer must ,again be 'broughtito half cocked position in orderto permitithe opening of the breech bydownward pressure on the finger piece 20. VAs the breech is opened theeXtractor is moved rearwardly thereby withdrawing .the fired shell tof-the positionf shown yin Fig. 2 from which 'itxcan be manually removed. Theftoe 34 ofthe :extractor overlies the shoulder 35 in. all positions of the mechanism and when :the fgun is taken down by withdrawing the take down screw from lplug 45 and removing'the barrel and forearmthis engagement of the extractor toe with the receiverholds not only the eX- tractorbut also the breech 'block and athe :fir-- ing spring in proper position. Accidental displacemen'tand loss of anyfpartfof the Lfire control mechanismy when the gun is staken down is thus prevented.
